Hacked Transmissions is a pioneering exploration of how social movements change across cycles of struggle and alongside technology. Weaving a rich fabric of local and international social movements and media practices, politicized hacking, and independent cultural production, it takes as its entry point a multiyear ethnography of Telestreet, a network of pirate television channels in Italy that combined emerging technologies with the medium of television to challenge the media monopoly of tycoon-turned-prime minister Silvio Berlusconi.
